My invention relates to improvements in gauges for positioning chills orcores on sand molds.

The object of my invention is to provide a gauge adapted to cooperatewith the guide pins of the drag of a sand mold, whereby the chills maybe accurately and quickly positioned in the supports in the drag, inrespect to the ends and sides of thedrag.

Another object of my invention is to pro-' vide a gauge of thischaracter which is readily placed over the guide pins of the drag nowused for guiding the cope thereon, so that it will at all times assume avery accurate position in respect to the sides and ends of the drag, sothat the chills and sand core are properly positioned on the drag.

A further object of my invention is to provide a simple, cheap andeffective gauge of this character having certain details of structureand combination of parts hereinafter more fully described.

In the accompanying drawings Figure 1 is a top plan view of a dragshowing my improved gauge applied thereto show' ing four chills properlypositioned thereon by my improved gauge.

Figure 2 is a top plan view similar to Figure 1 showing the sand coreproperly positioned thereon by another form of gauge.

Figure 3 is a vertical sectional view of a drag showing the chills andsand core properly positioned thereon by the gauge, and the cope inposition thereon.

Inthe manufacture of cylinder heads or other castings where chills andsand cores are used it has consumed considerable time toaccuratelyposition the chillsand sand cores on the drag in their properposition in respectto each other and to the sides and ends of the drag,but by my improved gauge it isa very simple matter to properly andrapidly position the chills and sand cores on the drag in respect toeach other, and to the sides and ends of the drag.

Referring now to the drawings, 1 represents any ordinary drag, which isprovided with the usual guide pins 2 and 3 at its ends which cooperatewith the eyes carried by the cope, all of which is well understood andneeds no further description. 1 improved gauge consists ofan elongatedbar A, ,of a length slightly greater than the length of the .drag and isprovided at each end with the laterally turned 611(1855 and 6, the innerfaces of which areprovided with the vertically disposed V shaped notchesf7 and 8 corresponding with the outer faces of the guide pins 2 and 3carried by the drag 1. The elongated bar 4;, at proper intervals, isprovided with outwardly extending lugs 9, 10, 11 and 12, ,ad=apted toserve as stops and means for proper positioning of the four chills E13,14, i and 16 in their proper position upon the supports carried by thedrag, such as shown in my copending application tiled July 56, 1928,Serial No. 290,822, and thus it will :be seen that the chills arerapidly and accurately positioned ,upon the chill supports carried bythe drag.

In Figure 2, I shown the same principle involved in iwhich thelbar 4hasasingle projection or ing 117 which is adapted to position the sandcore 18 on the drag. lnthe use of this gangs it will be understood thatas the chills are first placed on the chill supports in approximatelytheir proper position, and the gauge is lowered down over the guide pins2 and 3 of the drag-until it rests firmly upon the upper end walls ofthe drag the sameas the form shown in Figure l. A soft tool is used totap the chills up against the lugs 9, 10, 11 and 12, and when in contactwith the said lugs the chills are in their proper position over thechill supports. hen using my improved gauge for positioning the sandcore the gauge is first lowered over the guide pins of the drag and thecore 18 is then placed in position with one side which is supportedabove the upper face of the drag as shown in Figure 3.

Having thus fully described my invention what I claim is 1. A gaugeadapted to cooperate with the 'uide pins of a mold drag, and havin meansfor determining the position of the chills on the drag.

2. A gauge adapted to slide over the guide pins of a mold drag andhaving stops adapted to determine the position of the chills on thedrag.

3. A gauge adapted to coo erate with the drag, and having means foretermining the position of the chills on the drag.

4. A gauge of the character described comprisin an elon ated memberhaving laterally turne ends a apted to cooperate with the guide pins ofthe drag, and having means for determining the proper position of thechills on the drag.

5. A gauge of the character described comprising an elongated memberhaving laterally turned ends having vertically disposed ooves adapted tocooperate with the outer aces of the guide pins of the drag, and havingmeans for determining the proper position of the chill on the drag.

6. A gauge of the character described comprising an elongated flat barhaving laterally turned ends adapted to extend inwardly beyond the guidepins of the drag, and having vertically disposed rooves adapted toreceive the outer faces of tie guide pins, and means carried by said barand extending inwardly toform stops for determining the proper positionof the, chills on the drag.

In testimony whereof, I have signed this specification.
